LASTIC FILLING MATERIAL FOR CYCLE-TIRES, 80C.

Application filed April 22, 1897. Serial No. 638,393. (No specimens.)

To @ZZ whom t may concern:

Be it known that I, JULIUs DEBORDE, a citizen of the German Empire, residing at Berlin, in the Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in the Manufacture of Elastic Fillings for Cycle-Tires, Saddles, Cushions, dac., (for which Letters Patent have been granted to me in Germany, No. 95,260, dated March 11, 1897; in Sweden, No. 8,232, dated April 9, 1897; in France, No. 265,897, dated April 10, 1897; in Belgium, No. 127,515, dated April 10, 1897; in England,No. 8,905, dated April 7, 1897; in Austria, No. 2,450, dated April 9, 1897 5 in Norway, No, 6,042, dated June 8, 1897; in Hungary, No. 9,726, dated June l5, 1897; in Switzerland, N0. 14,777, dated June l, 1897 in Italy, No. 44,956, dated June 30, 1897; in Luxemburg, No. 2,867, dated June Ll, 1897, and in Spain, No. 20,995, dated June 1l, 1897,) of which the following is a speciiication.

This invention relates to an improved elastic filling or padding for tires of all kinds, saddles, cushions, dac. and the invention consists of a filling for tires, rbc., consisting of a spongy jelly-like substance formed, essentially, of a glue solution that is changed by mechanical treatment into a foamy condition.

In the accompanying drawings, Figure 1 is a vertical transverse section through a bicyclesaddle, the cushion of which is made of the improved material forming the subject-mat ter of this invention; and Fig. 2 is a vertical transverse section of a tire which is filled with my improved elastic material.

Referring to the drawings, a in Fig.- 1 represents the filling of a saddle pad or cushion of suitable shape, c the saddle-base, and b the covering.

In Fig. 2, .a represents the wheel-rim, upon which is secured the tire, having an outer portion o, an inner portion s, and a filling a of my improved material.

In making my improved filling for tires and other articles the filling is formed from a suitable jelly or other glue-like substance which has been transformed into a spongy condition. For this purpose a jelly of glue, gelatin, or like substance, or a mixture of glue with other substances is liquefied by heat and beaten up while in liquid condition by means of agitators, stirrers, centrifugal apparatus, or otherwise into foam. This foam is applied into tires, cushions, or other articles formed of leather, soft rubber, oil-cloth, or other suitable material and then converted into a rigid stateby cooling. After cooling the foam-like jelly appears to be permeated bya very large number of small cavities iilled with air, by which the elasticity of the mass, which in itself is elastic, is considerably increased and the Weight of the same diminished.

To prevent the hardening of the jelly, especially when sameis made from glue or gelatin, glycerin is added, and in addition thereto an antiseptic substance, by which the fermentation can be prevented. In place of forc ing the spongy mass directly into tires, cushions, and other objects the same can first be cast in suitable forms which can be, after cooling, transferred into a suitable sheath of soft leather or other material. The elasticity and the small weight of the objects Which are filled in this manner with foam-jelly can be still more increased when a number of small balls of soft rubber and rubber tubes or hollow elastic bodies are introduced into the mass before the cooling of the same.

The foam-jelly, which is produced in the manner herein described, can also be used to advantage as a filling for the tires of vehicles, saddles, handles, and cushions of all kinds. These cushions are durable, do not become rigid, non-elastic, or hardened, and can .be manufactured at a considerably small eX- pense. is that they are good conductors of heat, and consequently quite cool in use.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. An elastic filling for tires, saddles, cushions and other articles, consisting of a spongy foam -jelly formed of a mixture of gelatin and glycerin, substantially as set forth.

2. An elastic filling for tires, saddles, cushions and other articles, consisting of a spongy foam jelly formed of a mixture of gelatin, glycerin and an antiseptic substance, substantially as set forth.

3. The process herein described of making a spongelike filling for tires, saddles, cushions and other articles, which consists in sub- One of the advantages of the same IOC) bodies, casting or forming the mass into suitable shape, and cooling the same, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my naine in presence of two subscribing Witnesses.
